Parbati-Kalisindh-Chambal link project envisages the diversion of surplus waters of Parbati and Kalisindh sub-basins to Gandhisagar dam /Rana Pratap Sagar dam across Chambal River. The water will be utilized for irrigation in the new command areas enroute the link canal & the existing command of Chambal system at Kota barrage. Water of the Chambal thus saved by way of substitution will be tapped in the upper reaches and will be utilised in the drought prone districts of Upper Chambal sub-basin, where the present level of irrigation is 5.44% of culturable area. The link proposal involves three alternatives studies viz.(i) linking to Rana Pratap Sagar Dam [ Alt-(a)],(ii) linking to Gandhi Sagar Dam [ Alt-(b)-I] and linking to Gandhi Sagar Dam [ Alt-(b)-II].

In case of linking to Rana Pratap Sagar dam, the surplus water will irrigate an area of 1.09 lakh ha, out of which0.43 lakh ha area lies in Jhalawar, Kota & Chittorgarh districts of Rajasthan and 0.66 lakh ha area in Rajgarh, Guna, Shajapur (drought prone) and Mandsaur Districts of Madhya Pradesh and 1.12 lakh ha by substitution in Dhar(drought prone ) , Shajapur (drought prone ),Ujjain (drought prone ),Ratlam districts in the upper reaches of Chambal basin in Madhya Pradesh .

In case of linking to Gandhi Sagar dam, alt-(b)-I,the surplus water will irrigate an area of 1.19 lakh ha enroute, out of which 0.25 lakh ha is inJhalawar district of Rajasthan and 0.94 lakh ha area in Rajgarh, Guna, Shajapur (drought prone) and Mandsaur Districts of Madhya Pradesh and 1.12 lakh ha by substitution in Dhar(drought prone ), Shajapur (drought prone ),Ujjain (drought prone ),Ratlam districts in the upper reaches of Chambal basin in Madhya Pradesh.

In case of linking to Gandhi Sagar dam, alt-(b)-II,the surplus water will irrigate an area of 1.17 lakh ha enroute, out of which 0.27 lakh ha is inJhalawar district of Rajasthan and 0.90 lakh ha area in Rajgarh, Guna, Shajapur (drought prone) and Mandsaur Districts of Madhya Pradesh and 1.12 lakh ha by substitution in Dhar(drought prone ) , Shajapur (drought prone ),Ujjain (drought prone ),Ratlam districts in the upper reaches of Chambal basin in Madhya Pradesh.

Technical Aspects

The surplus water available at Patanpur, Mohanpura and Kundaliya is of the order of 948 Mcum, 444 Mcum and 610 Mcum respectively. It is proposed to divert 1360 Mcum of water through Parbati-Kalisindh-Chambal link project for meeting the requirement of seven projects in Upper Chambal basin, the enroute demands of link for irrigation & domestic use and additional requirement of Kota Barrage.

The total length of the link canal in case of linking to Rana Pratap Sagar dam is 243.62 km which includes 5 tunnels having total length of 20.56 km.The total cost of the project estimated at 2002-03 price level is Rs.2989.02 crores.The B.C. ratio has been worked out as 1.67.

The total length of the link canal from Patanpur dam to Gandhi Sagar dam in case of linking to Gandhi Sagar dam, alt-(b)-II, is 201.83 km which includes 3 tunnels having total length of 11.0 km and 3.2 km long pipeline to feed the sump well, involving single stage lift of 47.42mutilizing 18.10 MW of powerfor pumping whereas 9.07 MW of power is likely to be generated by transferred water at Gandhisagar dam. Thus, net requirement of power for pumping will be about 9.03 MW. The actual head in this case for single stage pumping is calculated as 62.41m.The total cost of the project estimated at 2002-03 price level is Rs.3058.30 crores.The B.C. ratio has been worked out as 1.63.

Environmental Issues

This project envisages construction of three dams viz. Patanpur on Parbati, Mohanpura on Newaj and Kundaliya on Kalisindh involving total submergence area of 17,308 ha including 244.4 ha forest area.A population of 27,055 people in 65 villages is likely to be affected. The works of Rapid Socio-Economic, Environmental & Ecological Impact studies awarded to M/s RITES Ltd. is under progress.
